Fission and Fusion

The splitting of a nucleus into smaller nuclei is

• fusion
• fission
• decay
• gamma radiation

This happens naturally due to an unstable nucleus.

• fission
• fusion
• radioactive decay
• K-capture

This is an example of...

• Chain reaction

• Fusion reaction

• Decomposition reaction

• Decay

Where does fusion occur naturally?

• Underwater
• All around us
• In the radioactive waste
• On the sun

Which of the following is true about nuclear fusion?

• It is easy to implement.
• It produces less energy than nuclear fission.
• It produces more energy than nuclear fission.
• It has the ability to occur easily in everyday life.

Takes two small nuclei and combines them into a larger nucleus

• fission
• fusion

In which process does a heavy nucleus split into two lighter nuclei?

• freezing

• condensation

• fission

• fusion

What occurs in both fusion and fission reactions?

• Small amounts of energy are converted into large amounts of matter.

• Small amounts of matter are converted into large amounts of energy.

• Heavy nuclei are split into lighter nuclei.

• Light nuclei are combined into heavier nuclei.

Which phrase describes a risk associated with producing energy in a nuclear power plant?

• depletion of atmospheric hydrogen

• depletion of atmospheric carbon dioxide

• production of wastes needing long-term storage

• production of wastes that cool surrounding water supplies
